■ Worldview: In 2038, South Korea completes extinct organism restoration technology and proceeds with the 'Cretasia Project' on Taebaek Bio Island, a secret artificial island in the East Sea. The dinosaurs restored for tourism, research, and military use escape control due to an unexpected accident, and the island instantly turns into a hunting ground for dinosaurs rather than humans. The government deploys the Special Disaster Response Unit to rescue survivors and suppress the situation, but a struggle for human survival begins amidst a massive conspiracy and the threat of apex predators.
